Staunton Spectator

The Stevens Exploring Party. —Governor Stevens, the head of the Northern Pacific Railroad Surveying party, writes an interesting letter to the Boston Post, giving an account of his operations. He writes from Fort Union, at the mouth of the Yellow Stone River, under date of August 7th. From that point his company were going on to Fort Benton in two parties—one carrying supplies for the route west of that place. They calculated to reach Fort Benton during the first days of September. Gov. Stevens says that his most sanguine expectations have been realized.—His command are in admirable condition, and his animals are in first rate order. An immense amount of material is being collected to figure in the report. He speaks of meeting the two Red River hunting parties—the one numbering fourteen hundred men, and the other two thousand. The buffalo herds through which the party have passed have been "countless," and Governor Stevens speaks of the scene on a certain Sunday, when the party ascended a high hill, and on every side, so far as the eye could reach, these herds were "moving like the undulations of the sea."
